"Taken together, our results indicate that LLLT can stimulate bone remodeling reducing root resorption in a rat model. LLLT improves tooth movement via bone ...
"In conclusion, it can be suggested that the resistance exercise program stimulated bone metabolism, culminating in increased cortical tibial area, bone mineral content, bone ...
"A circular defect in each parietal bone of six Wislander rats was created. The animals were divided into two three-unit subgroups. The experimental group ...
"A significant increase in DNA synthesis was observed at the wavelengths of 632.8, 635 and 830 nm, depending on the energy density level. A ...
"In conclusion, LA promotes longitudinal bone growth in adolescent rats, suggesting that laser acupuncture may be a promising intervention for improving the growth potential ...
"The LLLT was effective to stimulate osteoblastogenesis but failed to increase bone formation. Graft augmentation for treatment of bone defects seems essential for proper ...
"The InGaAsP laser at the low dosage induced a favorable effect on bone formation in the orthopedically expanded midpalatal suture of rats."
"Within the limitations of this study, it can be concluded that the PBM protocol used provided adjunctive effect on osteogenesis and may compensate the ...
"Greater new bone formation and a lower degree of inflammation were observed in the animals that had bone neoformation at the center of the ...
"We conclude that LLLT stimulated bone neoformation and contributed to an increase in the total number of osteocytes, especially with a laser energy density ...
"The results showed that Col could be successfully introduced into BG/Mg and the association of BG/Mg/Col and LLLT constituted an optimized treatment for accelerating ...
"In intergroup comparison, group 1 (mean ± SD= 45.2 ± 18.56%) showed a lower bone formation compared with groups 2 (64.13 ± 3.51%) (p = 0.358) and 4 (15.2 ± 78.22%) (p = 0.049), at ...
"It was concluded that the support system formed by the xenograft fibrin sealant associated with the photobiomodulation therapy protocol had a positive effect on ...
"It is concluded that the use of either laser or LED phototherapy associated to MTA cement was efficacious on improving the repair of complete ...
"Histological analysis confirmed the histomorphometric results, with the experimental groups showing bone neoformation of significantly higher quality and quantity at the end of 30 ...
"PBM significantly increased volumes of total callus, total bone, bone marrow, trabecular bone, and cortical bone, and the numbers of osteocytes and osteoblasts of ...
"The use of LLLT in activation period of distraction osteogenesis stimulates bone repair in the early stages of distraction osteogenesis by inducing intramembranous healing ...
"All groups had greater area of newly formed bone compared to group C (9.96±4.49%). The group PBMT+M (achieved the greater quantity of new bone ...
"The laser PBM also showed positive effects on the bone repair process with increased deposition and organization of the newly formed bone. However, laser ...
"The LLLT, in the present application protocol, did not increase the area of new bone formation when associated with autogenous bone or bioactive glass."
"The animals treated with LLLT exhibited increased mineralized tissues and bone, particularly after 90 days. These increases were associated with increased BMP2, OCN, and ...
"Findings suggest that in this study, laser treatment did not enhance callus formation nor reduce repair time of complete fracture of the radius in ...
"LLLT reduces inflammation and contributes to increased bone formation. PC treatment was shown to maintain connective tissue and to induce fibrosis during bone repair. ...
"DM group had significantly smaller bone area and lower blood vessel count when compared to DM + LLLT, CONT and CONT + LLLT groups ...
"As a conclusion, animals treated with BS/PLGA+LLLT demonstrated an improved material degradation and an increased amount of granulation tissue and newly formed bone."
"Compared to the [control] group, defects in the 30-day [LLLT] group exhibited increased bone formation, both by increase in radiopaque areas (P < 0.01) ...
"It can be concluded that LED therapy positively influences bone formation in the early stages of the bone repair process in non-diabetic and diabetic ...
"Analysis of variance (ANOVA) (p = 0.013) results showed that treatment by PBM significantly increased the biomechanical property (stress high load) of the callus ...
"These results indicated that the use of laser phototherapy improved the repair of bone defects grafted with the biomaterial by increasing the deposition of ...
"The sessions of laser irradiation decreased inflammatory process severity, activated fibrillogenesis and angiogenesis, accelerated the compactization of newly formed bone tissue, and enhanced its ...
"No significant change was observed in the number of osteocytes, osteoblasts, osteoclasts and newly formed vessels at either time period across all laser groups. ...
"Nicotine harms bone formation in the bed-graft interface and LLLT action can mitigate this."
Comment: There seems to be an error in the reporting of ...
"No significant difference in new cartilage formation and inflammation was found between the groups (p > 0.05). However, there was significantly more new bone ...
